DETAILED DESCRIPTION

The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail.

Embodiments described herein may relate to accessing a secured entity via a credential saved on device. As one example, a user may have a credential stored on their phone that allows the user to unlock a door of their house. For example, the user may unlock the door by moving their phone within a proximity of a lock on the door of the house or by interacting with their phone to indicate that the user wants to unlock the lock of the door. To provide security to the user in some instances, the credential for unlocking the door will be prevented from being directly copied from the phone. For example, the credential may need to be generated by a credential manager that provides the credential to the phone.

However, a user may want to allow another user to be able to unlock the door on their house. For example, the user may want to be able to allow a house guest to unlock and lock the door on their house so the house guest can come and go as they please. To allow the house guest to unlock the door, the user may want to share the credential with the house guest that will allow the guest to unlock the door. Although, the phone may not be able to generate copies of the credential or providing the credential stored on their phone.

In embodiments described herein, the user may request that the credential manager generate another copy of the credential for the house guest. The credential manager may generate another copy of the credential for use by the house guest. A phone of the house guest may retrieve the credential from the credential manager. The credential manager may authenticate the house guest to verify that the house guest is authorized to receive the credential before providing the credential to the phone of the house guest. Once the phone of the house guest receives the credential, the house guest may be able to unlock the door using their phone.

Embodiments described herein may include sharing of a credential by an origination device with a recipient device. In particular, a credential for access to a secured entity may be provisioned to the origination device, such as being provisioned by a credential manager. The origination device may be unable to clone or create a copy of the credential for sharing with the recipient device, such as when the credential is unclonable and/or the recipient device is executing a different platform than the origination device. The origination device may communicate with a relay server to store a token to be retrieved by the recipient device. The recipient device may utilize the token to obtain the credential to be used for accessing a secured entity associated with the credential.

For example, a user of the origination device, having the credential stored thereon, may request that a credential manager for the credential to generate the credential for use by the origination device. The credential manager may generate another of the credential for use by the recipient device. The origination device may then generate a password and provide the password to the recipient device. The recipient may utilize the password to retrieve the credential from the credential manager.

FIG. 1 illustrates an example credential arrangement 100 in accordance with some embodiments. The credential arrangement 100 shows a portion of the entities that may be utilized to share a credential between an origination device 102 and a recipient device 104. The credential arrangement 100 illustrates example high level concepts of credential sharing between the origination device 102 and the recipient device 104, where further description below provides further details of the credential sharing.

The credential arrangement 100 may include the origination device 102. The origination device 102 may include one or more of the features of the user equipment (UE) 1200 (FIG. 12 ). The origination device 102 may include wireless circuitry that allows the origination device 102 to wirelessly access secured entities. For example, the origination device 102 may provide access to a secured entity when the origination device 102 is moved within a proximity of the secured entity or user interaction with the origination device 102 indicates that the origination device 102 is to provide access to the secured entity.

The credential arrangement 100 may include a secured entity 106. The secured entity 106 may include a vehicle, a building, a room, an electronic storage location, and/or another secure physical entity or secure computer entity. The secured entity 106 may be inaccessible, or may have some portion that is inaccessible, without a credential. The secured entity 106, or some portion thereof, may be wirelessly enabled for wireless communication with other devices. The secured entity 106 may detect a credential associated with the secured entity 106 received from another device (such as the origination device 102) and may provide access to the secured entity 106, or some portion thereof. The credential may comprise an electronic credential that can be used for authenticating that a user is authorized to access the secured entity 106.

The credential arrangement 100 may include a credential manager 108 (which also may be referred to as a credential authority). The credential manager 108 may generate, store, and/or assign credentials for one or more secured entities. In the illustrated embodiment, the credential manager 108 may be associated with the secured entity 106 and may generate, store, and/or assign credentials for the secured entity 106. For example, the credential manager 108 may be communicatively coupled to the secured entity 106 and may provide the secured entity 106 with indications of credentials for which the secured entity 106 is to provide access. The credentials generated, stored, and/or assigned by the credential manager 108 may provide for access to the secured entity 106 when detected by the secured entity 106.

The credential manager 108 may generate one or more credentials for the secured entity 106 and may provide the credentials to one or more other devices for providing access to the secured entity 106. In the illustrated embodiment, the credential manager 108 may have generated a credential 110 for accessing the secured entity 106. Further, the credential manager 108 may have assigned the credential 110 to the origination device 102 to provide the origination device 102 with access to the secured entity 106. Assigning the credential 110 may include the credential manager 108 providing the credential 110 to the origination device 102 for storage on the origination device 102. The credential manager 108 may establish a wireless connection and/or a network connection with the origination device 102 to provide the credential 110 to the origination device 102 in some embodiments. The credential manager 108 may further indicate the credential 110 to the secured entity 106, thereby indicating to the secured entity 106 that the secured entity 106 is to allow access when the credential 110 is detected by the secured entity 106. In some embodiments (such as when a user of the origination device 102 owns the secured entity 106), the credential manager 108 may be implemented within the origination device 102.

The credential 110 may comprise an unclonable credential in some embodiments. For example, the credential 110 may comprise an unclonable digital key. The credential 110 may be tied to the particular device to which the credential 110 is assigned (the origination device 102 in the illustrated embodiment) in some embodiments such that other devices may be unable to utilize the credential to access the secured entity 106. In some embodiments, the credential 110 may be designed such that if a device tries to copy the credential 110, the copy of the credential 110 will not be the same as the credential 110. Accordingly, the origination device 102 may be unable to produce a copy of the credential 110 to provide to other devices for providing access to the secured entity 106. Therefore, the origination device 102 may be unable to directly assign the credential 110 to other devices for providing access to the secured entity 106.

The credential arrangement 100 may further include the recipient device 104. The recipient device 104 may include one or more of the features of the UE 1200 (FIG. 12 ). The recipient device 104 may include wireless circuitry that allows the recipient device 104 to communicate with one or more other devices. In some embodiments, the recipient device 104 may be executing a different platform from the origination device 102. For example, the origination device 102 may be executing a first operating system (such as operating systems iOS, Android, Windows, MacOS, Linux, or other operating systems) while the recipient device 104 is operating a second operating system that is different from the first operating system. Due to the origination device 102 and the recipient device 104 executing different operating systems, communication between the origination device 102 and the recipient device 104 may include translation of the communication to the standards of the device receiving the communication.

Unlike the origination device 102, the recipient device 104 may not have been originally assigned the credential 110 from the credential manager 108. However, there may be times at which a user of the origination device 102 may wish to share the credential 110 with the recipient device 104 to allow the recipient device 104 to provide access to the secured entity 106. The origination device 102 may be unable to share the credential 110 directly with the recipient device 104 due to the credential being unclonable and/or the origination device 102 and the recipient device 104 executing different platforms. Therefore, the approaches described further throughout this disclosure for sharing the credential may be implemented for the origination device 102 to share the credential 110 with the recipient device 104. Once the credential 110 is shared with the recipient device 104 in accordance with the approaches, the recipient device 104 may provide access to the secured entity 106, such as when the recipient device 104 is moved within a proximity of the secured entity 106 or user interaction with the recipient device 104 indicates that the recipient device 104 is to provide access to the secured entity 106.

FIG. 2 illustrates a first portion of an example signal flow 200 for sharing a credential in accordance with some embodiments. In particular, the signal flow 200 indicates signals and operations that may be performed for sharing a credential between a first device (referred to as “origination device”) and a second device (referred to as “recipient device”). Some of the signals and/or operations illustrated may be implemented in the alternative, as described further herein. Further, it should be understood that the signals and/or operations, or some portions thereof, may be performed concurrently and/or some of the signals and/or operations may be omitted in embodiments.

The signal flow 200 may be implemented among multiple entities that facilitate the sharing of the credential between the origination device and the recipient device. For example, the signal flow 200 may include a user information application 202 being executed by the origination device. In some embodiments, the user information application 202 may be a wallet application, where the wallet application may retrieve account information and/or balance information from a credential manager and represent the account information and/or balance information on the origination device. The origination device may be, or may include one or more of the features of, the origination device 102 (FIG. 1 ). The user information application 202 may store one or more credentials that allow the origination device to access a secured entity. For example, the user information application 202 may have been assigned, and have stored, a credential (such as the credential 110 (FIG. 1 )). The credential may provide the origination device with access to a secured entity (such as the secured entity 106 (FIG. 1 )). The origination device may share the credential with the recipient device via the signals and operations illustrated in the signal flow 200.

The signal flow 200 may further include a communication application 204. The communication application 204 may comprise an application executed on the origination device that can be utilized by the origination device to communicate with another device. For example, the communication application 204 may comprise a text messaging application in some embodiments. Some examples of the communication application 204 may include short message service (SMS), multimedia messaging service (MMS), WhatsApp, Signal, Telegram, iMessage, Google Messages, and other messaging services. The origination device may utilize the communication application 204 to communicate with communication applications executing on other devices.

The signal flow 200 may include a provisioning server 206. The provisioning server 206 may be associated with the origination device and may be responsible for provisioning credentials to the user information application 202 of the origination device. For example, the provisioning server 206 may have provisioned the credential to the user information application 202 for accessing the secured entity. In some embodiments, the provisioning server 206 may comprise an Android Broker, an Apple Broker, or another provisioning server.

The signal flow 200 may include a push notification system 208. The push notification system 208 may be utilized for issuing pushes for the origination device and/or issuing pushes between the origination device and one or more other devices. For example, the push notification system 208 may provide messages to the origination device that can cause the origination device to perform an operation, such as display a user interface pop up in a heads-up manner on the origination device in response to the origination device detecting the messages and/or perform another operation.

The signal flow 200 may include a relay server 210. The relay server 210 may be associated with the origination device and may facilitate the sharing of credentials with devices executing different platforms. The relay server 210 may receive data from the origination device and make the data available to devices executing other platforms. For example, the relay server 210 may receive the data from the origination device and may convert the data to a format for a different platform requesting the data. For example, the relay server 210 may receive a token from the user information application 202 and convert the token for a different platform when another device retrieves the token.

The signal flow 200 may include a credential manager 212. The credential manager 212 may include one or more of the features of the credential manager 108 (FIG. 1 ). The credential manager 212 may be associated with one or more secured entities (such as the secured entity 106) and may generate, store, and/or assign one or more credentials (such as the credential 110 (FIG. 1 )) for the secured entities. For example, the credential manager 212 may have assigned the credential to the user information application 202 of the origination device that is to be shared with the recipient device via the signals and/or operations of the signal flow 200.

The signal flow 200 may include a push notification system 214. The push notification system 214 may be utilized for issuing pushes for the recipient device and/or issuing pushes between the recipient device and one or more other devices. The recipient device may be, or may include one or more of the features of, the recipient device 104 (FIG. 1 ). The push notification system 214 may provide messages to the recipient device that can cause the recipient device to perform an operation, such as display a user interface pop up in a heads-up manner on the recipient device in response to the recipient device detecting the messages and/or perform another operation.

The signal flow 200 may include a web application 216. The web application 216 may facilitate provisioning of credentials into a user information application 222 of the recipient device. For example, the web application 216 may communicate with the credential manager 212 to facilitate sharing the credential with the recipient device.

The signal flow 200 may include a provisioning server 218. The provisioning server 218 may be associated with the recipient device and may be responsible for provisioning credentials to the user information application 222 of the recipient device. In some embodiments, the provisioning server 218 may comprise an Android Broker, an Apple Broker, or another provisioning server. The recipient device may be executing a different platform than the origination device and the provisioning server 218 may be provisioning in accordance with the platform executed by the recipient device. For example, if the provisioning server 206 is an Android Broker, the provisioning server 218 may be an Apple Broker in some embodiments.

The signal flow 200 may include a communication application 220. The communication application 220 may comprise an application executed on the recipient device that can be utilized by the recipient device to communicate with another device. For example, the communication application 220 may comprise a text messaging application in some embodiments. Some examples of the communication application 220 may include short message service (SMS), multimedia messaging service (MMS), WhatsApp, Signal, Telegram, iMessage, Google Messages, and other messaging services. The recipient device may utilize the communication application 220 to communicate with communication applications executing on other devices.

The signal flow 200 may include a user information application 222 being executed by the recipient device. In some embodiments, the user information application 222 may be a wallet application, where the wallet application may retrieve account information and/or balance information from a credential manager and represent the account information and/or the balance information on the recipient device. The recipient device may be, or may include one or more of the features of, the recipient device 104. The recipient device may execute a different platform than the origination device. The user information application 222 may be a user information application for the platform executed by the recipient device, whereas the user information application 202 may be a user information application for the platform executed by the origination device. The user information application 222 may store one or more credentials that allow the recipient device to access a secured entity.

In 224, the user information application 202 of the origination device may detect a user interaction from a user of the origination device that indicates the user desires to share a credential. For example, the user information application 202 may be executed by the origination device and may present a user interface on a display of the origination device. The origination device may detect a user indication with the user interface displayed by the origination device that indicates the user desires to share a credential.

In 226, the user information application 202 may read shareable entitlements from the origination device. For example, the user information application 202 may determine credentials that are available in the user information application 202, which may be one or more of the credentials stored by the origination device. From the credentials, the user information application 202 may determine which of the credentials are shareable. For example, stored data associated with the credentials may indicate which of the credentials are shareable in some embodiments.

In 228, the user information application 202 may present indications of the shareable credentials to the user of the origination device. In particular, the user information application 202 may display a user interface on the display of the origination device that indicates the credentials available in the user information application 202 that are shareable. The user interface may allow the user to select one or more of the shareable credentials to be shared by the user information application 202.

In 230, the user information application 202 may detect a user interaction from the user that indicates which of the shareable credentials the user selects to share. For example, the user may interact with the user interface display by the user information application in 228 to indicate which of the displayed shareable credentials the user selects to share. The origination device may detect the user interaction and the user information application 202 may determine which credentials are to be shared based on the user interaction. In some embodiments, the user may further define limitations for sharing of the credentials. For example, the user may indicate a time period for which the sharing of the credentials is to remain valid, times of day and/or week that a device with which the credentials are being shared may utilize the credentials, a particular entity access point (for example, if a secured entity includes multiple entity access points (such as multiple doors), a particular entity access point (such as a certain door of the multiple doors) may be defined for providing access to the secured entity), or other limitations for the use of the credentials.

In 232, the user information application 202 may detect a user interaction from the user indicating that the sharing of the selected credentials is to be initiated. For example, the user may interact with a user interface displayed on the display of the origination device that indicates that the user information application 202 is to share the selected credentials. The user information application 202 may detect the user interaction and initiate the procedure for sharing the credentials.

234 through 244 and 302 (FIG. 3 ) may be performed in the alternative in different embodiments. For example, 234 through 244 may be performed in some instances and 302 may be performed in other instances. 234 through 244 may be performed in instances where the credential authority is located remote from the origination device, such as the credential manager 212 being implemented in a device separate from the origination device. 302 may be implemented in instances where the credential authority is implemented by the origination device.

In 234, the user information application 202 may transmit a sharing session request to the provisioning server 206. The sharing session request may request that a session be initiated for sharing the credentials selected in 230. The sharing session request may include authentication information for the origination device that may be utilized for authenticating the device for setting up the sharing session. In some embodiments, the authentication information may include fast identity online (FIDO) authentication information that can be utilized for authenticating the origination device. The sharing session request may further include entitlement information and/or serial number information related to the credential to be shared. For example, the entitlement information may indicate the credential and/or any limitations corresponding to the credential as may be defined in the selection in 230.

In 236, the provisioning server 206 may transmit a sharing session request to the credential manager 212. In particular, the provisioning server 206 may detect the sharing session request received from the user information application 202 in 234. The provisioning server 206 may utilize data included in the sharing session request received from the user information application 202 to generate a provisioning bundle identifier (ID). The provisioning server 206 may generate the provisioning bundle based on the serial number information received in the sharing session request received from the user information application 202, information related to the user information application 202, information related to the provisioning server 206, or some combination thereof. The provisioning server 206 may generate a sharing session request to be transmitted that includes the authentication information received from the user information application 202, the entitlement information received from the user information application 202, and/or the provisioning bundle. The provisioning server 206 may transmit the sharing session request generated by the provisioning server 206 to the credential manager 212.

In 238, the credential manager 212 may generate a token (which may be referred to as a “bearer token”) and/or metadata corresponding to the credential to be shared. For example, the credential manager 212 may detect the sharing session request received from the provisioning server 206. The credential manager 212 may perform authentication of the origination device based on information included in the sharing session request received from the provisioning server 206. If the credential manager 212 fails to authenticate the origination device, the procedure of sharing the credential may be terminated. If the credential manager 212 authenticates the origination device, the credential manager 212 may generate the bearer token and/or the metadata based on information received in the sharing session request. The metadata may include provisioning information related to the platforms executed by the originating device and/or the recipient device, generate advanced encryption standard (AES) data (such as AES salt) and/or data for stateful sharing of the credential. Stateful sharing may include the origination device and the recipient device communicating to share the credential. The credential manager 212 may bind the bearer token and/or the metadata to the entitlement information received in the sharing session request. The credential manager 212 may allow the credential to be retrieved based on the bearer token by a single device. The credential manager 212 may further encrypt the bearer token and/or the metadata. The encryption may prevent one or more of the entities (such as the provisioning server 206, the relay server 210, the web application 216, and/or the provisioning server 218) from being able to read the bearer token and/or the metadata.

In 240, the credential manager 212 may transmit the encrypted bearer token and/or the metadata to the provisioning server 206. The credential manager 212 may transmit the encrypted bearer token and/or the metadata based on receiving the sharing session request received from the provisioning server 206.

In 242, the provisioning server 206 may transmit the encrypted bearer token and/or the metadata to the user information application 202 on the origination device. Due to the encrypting, one or more of the entities (such as the provisioning server 206, the relay server 210, the web application 216, and/or the provisioning server 218) may be unable to read the bearer token and/or the metadata. The provisioning server 206 may forward the encrypted bearer token and/or the metadata received from the credential manager 212 to the user information application 202.

In 244, the user information application 202 may decrypt the bearer token and/or the metadata received from the provisioning server 206. In particular, the user information application 202 may detect the encrypted bearer token and/or metadata received from the provisioning server 206. The user information application 202 may decrypt the encrypted bearer token and/or metadata received from the provisioning server 206.

FIG. 3 illustrates a second portion of the example signal flow 200 for sharing a credential in accordance with some embodiments. In the alternative to 234 through 244, 302 may be performed in other instances. In 302, the user information application 202 may generate a token (which may be referred to as a “bearer token”) and/or metadata based on the indication to share the selected credentials. The bearer token and/or metadata may include one or more of the features of the bearer token and/or metadata described in relation to 238.

In 304, the user information application 202 may generate a password. The password may be utilized for retrieving the shared credential. For example, the origination device may provide the password to the recipient device, as described further throughout this disclosure, and the recipient device may utilize the password to retrieve the shared credential.

In 306, the user information application 202 may generate a mailbox ID. The mailbox ID may be utilized for storage of the bearer token and/or the metadata. For example, the bearer token and/or the metadata may be stored in association with the mailbox ID, where the bearer token and/or the metadata may be identified based on the mailbox ID. For example, the mailbox ID may be utilized to indicate a storage location of the bearer token and/or the metadata when stored.

In 308, the user information application 202 may generate a mailbox. For example, the user information application 202 may generate a mailbox associated with the mailbox ID. The mailbox may be utilized for storage of the bearer token and/or the metadata. The mailbox may comprise an application mailbox at a specified uniform resource locator (URL).

In 310, the user information application 202 may generate a key. The key generated by the user information application 202 may be a symmetric key. In some embodiments, the key may be an AES key. The user information application 202 may derive the key from the mailbox ID, the password, and/or salt from the metadata received from the provisioning server 206 and/or generated by the user information application 202. In some embodiments, the key may be further derived based on a number of iterations.

In 312, the user information application 202 may securely store the key with the mailbox. 312 may be performed as part of a stateful key exchange for stateful credential sharing. 312 may be omitted in stateless credential sharing. The key may be utilized to encrypt stateful payloads in the stateful credential sharing. The user information application 202 may store the key in a secure element of the origination device, where the secure element may comprise a chip within the origination device that is designed to be protected from unauthorized access. The secure element may limit a set of applications that are allowed to access the chip and/or write to the chip.

In 314, the user information application 202 may generate an encrypted payload. The user information application 202 may generate the encrypted payload by encrypting the bearer token and/or another token (which may be referred to as a “sender push token”). The user information application 202 may perform AES encryption with the bearer token and/or the sender push token to produce the encrypted payload. The encryption of the payload may prevent one or more of the entities (such as the provisioning server 206, the relay server 210, the web application 216, and/or the provisioning server 218) from being able to read bearer token and/or the sender push token.

In 316, the user information application 202 may provide the encrypted payload and/or the metadata to the relay server 210. The encrypted payload may include the bearer token in an encrypted format. The bearer token being in the encrypted format may prevent relay server 210 from being able to read the bearer token. The user information application 202 may provide configuration information and/or the mailbox ID along with the encrypted payload and/or the metadata. The configuration information may indicate authorization policies to be implemented by the relay server 210 when sharing the credentials. The available policies may include stateless (which may allow a single write), stateful (which may allow two writes), and/or long lived (which may allow infinite writes, signatures).

In some embodiments, the user information application 202 may further provide an attestation in 316. The attestation may comprise a signature applied to the data, or some portion thereof, transmitted in 316. The attestation may be associated with the origination device executing the user information application 202 and may be utilized for determining that the origination device is a valid device for requesting the sharing of the credential. The attestation may limit or be devoid of information that can identify a user of the origination device. Accordingly, the relay server 210 may be unable to identify a user of the origination device based on the attestation, which can protect the identity of the user and/or credentials associated with the user. The relay server 210 may utilize the attestation to determine that the device requesting the sharing of the credential is a type of device that is authorized to share the credential. For example, the relay server 210 may be aware that a smartphone device is authorized to share the credential. If the relay server 210 determines that the device requesting the sharing of the credential is a smartphone device based on the attestation, the relay server 210 may allow the signal flow 200 to continue. However, if the relay server 210 determines that the device requesting the sharing of the credential is another type of device (such as another server), the relay server 210 may terminate the signal flow 200. In some embodiments, the attestation may be omitted.

In 318, the relay server 210 may convert the metadata to rich object data. The metadata may include an indication of the secured entity to which the credential can provide access. A device may utilize the rich object data to display an indication of the secured entity on the device.

FIG. 4 illustrates a third portion of the example signal flow 200 for sharing a credential in accordance with some embodiments. In 402, the relay server 210 may store the encrypted payload and/or the rich object data produced from the metadata in a location associated with the mailbox ID. For example, the relay server 210 may store the encrypted payload received from the user information application 202 and/or the rich object data produced from the metadata, where the location can be identified based on the mailbox ID. Further, the relay server 210 may associate the authorization policy indicated by the configuration information in 316 with the storage location, such that the relay server 210 may apply the authorization policy for any device attempting to access the storage location via the mailbox ID.

In 404, the relay server 210 may provide a universal share URL to the user information application 202. The universal share URL may correspond to the storage location associated with the mailbox ID. A device that enters the universal share URL may be directed to the storage location and may, when authenticated, be able to retrieve information from the storage location. The relay server 210 may provide the universal share URL to the user information application 202 for sharing with the recipient device to retrieve the encrypted payload and/or the rich object data stored in the storage location.

In 406, the user information application 202 may launch the communication application 204 for sharing the universal share URL received in 404 and/or the password generated in 304. For example, the user information application 202 may cause the universal share URL and/or the password to be provided to the communication application 204 for sharing with another device, such as the recipient device. The user information application 202 may transmit the password out of band for increased security. For example, the user information application 202 may transmit the password in a different communication from the token to provide for increased security.

In 408, the communication application 204 associated with the origination device may transmit the universal share URL and/or the password to the communication application 220 associated with the origination device. For example, the communication application 204 being executed by the origination device may transmit the universal share URL and/or the password in a message to the communication application 220 being executed by the recipient device.

In 410, the communication application 220 associated with the recipient device may utilize the universal share URL received in 408 to request information from the relay server 210 associated with mailbox ID. For example, the communication application 220 may transmit a request to the relay server 210 to provide at least a portion of the information associated with the universal share URL, which may be the storage location on the relay server 210 associated with the mailbox ID.

In 412, the relay server 210 may provide the rich object data generated from the metadata to the communication application 220. For example, the relay server 210 may retrieve the rich object data from the storage location based on the request received in 410 and transmit the rich object data to the communication application 220 being executed on the recipient device.

In 414, the communication application 220 may display a snapshot corresponding to the rich object data on the display of the recipient device. For example, the rich object data may include an indication of the secured entity for which the shared credential may provide access. The communication application 220 may cause the indication of the secured entity to be displayed on the display of the device. The indication may include a description of the secured entity, an image associated with the secured entity, or some other visual representation related to the secured entity that may be displayed on the display of the recipient device.

In 416, the communication application 220 may provide the universal share URL and/or the password received in 408 to the user information application 222 executing on the recipient device. In some embodiments, the communication application 220 may provide the universal share URL and/or the password to the user information application 222 based on a user interaction with the indication of the secured entity displayed on the display of the device in 414. The communication application 220 may cause the user information application 222 to launch along with providing in the universal share URL and/or the password.

In 418, the user information application 222 may transmit a request to the relay server 210 to provide the information from the mailbox. For example, the user information application 222 may transmit a request that includes the mailbox ID indicating the mailbox from which the data is being requested.

In 420, the relay server 210 may provide the rich object data generated from the metadata and/or the encrypted payload to the user information application 222. The relay server 210 may provide the rich object data and/or the encrypted payload based on the reception of the request received from the user information application 222 in 418.

In 422, the user information application 222 may generate a key. In particular, the user information application 222 may generate the key based on the rich object data, the mailbox ID, the password, and/or iterations. The key may be a symmetric key in some embodiments. The user information application 222 may derive an AES key from the rich object data, the mailbox ID, the password, and/or the iterations to produce the key.

FIG. 5 illustrates a fourth portion of the example signal flow 200 for sharing a credential in accordance with some embodiments. In 502, the user information application 222 may decrypt the encrypted payload received in 420 with the key generated in 422. The user information application 222 may produce the bearer token and/or the sender push token by decrypting the encrypted payload.

504 through 614 (FIG. 6 ) may be performed in some instances and may be omitted in other instances. For example, 504 through 614 may be performed for stateful key exchanges, whereas 504 through 614 may be omitted for stateless key exchanges. Whether the exchange is stateful or stateless may be defined based on configuration defined in 316.

In 504, the user information application 222 may securely store the key produced in 422 with association to the mailbox ID. The user information application 222 may store the key in a secure element of the recipient device.

In 506, the user information application 222 may generate a key pair. For example, the user information application 222 may generate the key pair based on the metadata for provisioning information in accordance with key requirements. The key pair may be an asymmetric key pair in some embodiments, where the asymmetric key pair may comprise a public key and a corresponding private key.

In 508, the user information application 222 may encrypt the public key of the key pair generated in 506. The user information application 222 may perform AES encryption with the public key of the key pair.

In 510, the user information application 222 may transmit the public key of the key pair generated in 506 to the relay server 210. For example, the user information application 222 may transmit the encrypted public key, which was encrypted in 508, to the relay server 210. The user information application 222 may further transmit the mailbox ID and/or the sender push token to the relay server 210 with the encrypted public key. The relay server 210 may store the encrypted public key based on the reception of the encrypted public key.

In some embodiments, the user information application 222 may further provide an attestation in 510. The attestation may comprise a signature applied to the data, or some portion thereof, transmitted in 510. The attestation may be associated with the recipient device executing the user information application 222 and may be utilized for determining that the recipient device is a valid device for obtaining the shared credential. The attestation may limit or be devoid of information that can identify a user of the recipient device. Accordingly, the relay server 210 may be unable to identify a user of the recipient device based on the attestation, which can protect the identity of the user and/or credentials associated with the user. The relay server 210 may utilize the attestation to determine that the device requesting the shared credential is a type of device that is authorized to receive the credential. For example, the relay server 210 may be aware that a smartphone device is authorized to receive the credential. If the relay server 210 determines that the device requesting the credential is a smartphone device based on the attestation, the relay server 210 may allow the signal flow 200 to continue. However, if the relay server 210 determines that the device requesting the credential is another type of device (such as another server), the relay server 210 may terminate the signal flow 200. In some embodiments, the attestation may be omitted.

In 512, the relay server 210 may request a push notification from the push notification system 208 associated with the origination device. The push notification request may include the mailbox ID, the sender push token, and/or the public key. The push notification request may request that the push notification system 208 provide a push notification to the user information application 202 that indicates a recipient device is attempting to retrieve the shared credential.

In 514, the push notification system 208 may send a push notification to the user information application 202 on the origination device. The push notification may cause a user interface to be displayed on a display of the origination device. The user interface displayed on the origination device may indicate that a recipient device is attempting to retrieve the shared credential. In some embodiments, the user interface displayed on the origination device may further request input from a user of the origination device to indicate that the recipient device is authorized to receive the shared credential. By utilizing the push notification system 208, the notification may be provided when recipient device is attempting to retrieve the credential and/or as soon as the origination device is available to receive push notifications after the recipient device has attempted to retrieve the credential.

In 516, the user information application 202 may send a request to the relay server 210 to retrieve information from the relay server 210. The information requested by the user information application 202 may include the encrypted public key that was stored in 510.

In 518, the relay server 210 may transmit information to the user information application 202 based on the request from 516. For example, the relay server 210 may transmit the encrypted public key to the user information application 202.

In 520, the user information application 202 may decrypt the information received from the relay server 210. For example, the user information application 202 may decrypt the encrypted public key received in 518. The user information application 202 may decrypt the encrypted public key using a receiver push token. Decrypting the encrypted public key may produce the public key.

In 522, the user information application 202 may generate a signature. For example, the wallet key may generate a signature based on the bearer token, the public key, and/or the mailbox ID. The signature may cover the public key that was produced through the decryption in 520. In some embodiments, the signature may include an attestation, a token, and/or entitlements. In some embodiments, the signature may be used in place of the bearer token going forward in the signal flow 200.

FIG. 6 illustrates a fifth portion of the example signal flow 200 for sharing a credential in accordance with some embodiments. In 602, the user information application 202 may encrypt the signature to produce an encrypted payload. For example, the user information application 202 may encrypt the signature generated in 522 using AES encryption to produce the encrypted payload.

In 604, the user information application 202 may provide the encrypted payload to the relay server 210 for storage. The user information application 202 may further provide a nonce value (for example, the nonce value may be an arbitrary number), the receiver push token, and/or the mailbox ID to the relay server 210 with the encrypted payload. The relay server 210 may store the encrypted payload when received. For example, the relay server 210 may store the encrypted payload in a storage location corresponding to the mailbox ID. Due to the encrypted payload being encrypted, the relay server 210 may be unable to read the data within the encrypted payload.

In 606, the relay server 210 may transmit a request for a push notification to the push notification system 214 associated with the recipient device. The request may include the mailbox ID and/or the receiver push token.

In 608, the push notification system 214 may transmit a push notification to the user information application 222 executed by the recipient device. The push notification system 214 may transmit the push notification based on the request for the push notification received by the push notification system in 606. The push notification may cause a user interface to be displayed on a display of the recipient device. The push notification may include the mailbox ID and/or the receiver push token.

In 610, the user information application 222 may transmit a request for information to the relay server 210. For example, the user information application 222 may transmit a request for the relay server 210 to provide at least a portion of the information stored in the storage location corresponding to the mailbox ID.

In 612, the relay server 210 may transmit the encrypted payload stored in the storage location corresponding to the mailbox ID to the user information application 222. For example, the relay server 210 may transmit the encrypted payload stored in 604 to the user information application 222. The encrypted payload may include the encrypted signature.

In 614, the user information application 222 may decrypt encrypted payload received from the relay server 210 in 612. For example, the user information application 222 may perform AES decrypting with the encrypted payload. The decryption of the encrypted payload may produce the signature.

616 and 618 may be performed in the alternative in difference embodiments. For example, 616 may be performed in some instances and 618 may be performed in other instances. 616 may be performed in instances where a stateless key exchange is being performed. 618 may be performed in instances where a stateful key exchange is being performed. Whether the exchange is stateful or stateless may be defined based on configuration defined in 316.

In 616, the user information application 222 may launch an application programming interface (API) with the provisioning server 218 associated with the recipient device. The API may be utilized for eligibility for retrieving the shared credential. The user information application 222 may provide the bearer token and/or the rich object data received in 420.

In 618, the user information application 222 may launch an application programming interface (API) with the provisioning server 218 associated with the recipient device. The API may be utilized for eligibility for retrieving the shared credential. The user information application 222 may provide the bearer token, the rich object data received in 420, the signature produced in 614, and/or the mailbox ID.

In 620, the provisioning server 218 may transmit a redeem request to the web application 216. The redeem request may indicate a provisioning target for the redemption. The redeem request may include the mailbox ID, the bearer token, and/or the rich object data.

In 622, the web application 216 may extract a card template. For example, the web application 216 may utilize the rich object data to extract a card template. The card template may correspond to the credential to be retrieved.

FIG. 7 illustrates a sixth portion of the example signal flow 200 for sharing a credential in accordance with some embodiments. In 702, the web application 216 may determine a source of the credential. For example, the web application 216 may determine which credential manager manages credentials for the secured entity based on the card template extracted in 622. In the illustrated embodiment, the web application 216 may determine that the credential manager 212 manages the credential being shared.

In 704, the web application 216 may transmit a redeem request to the credential manager 212 determined in 702. The redeem request may indicate a provisioning target for the redemption. The redeem request may include the bearer token.

In 706, the credential manager 212 may transmit at least a portion of the information utilized by the credential manager 212 for providing the shared credential to the web application 216. In some embodiments, the information provided by the credential manager 212 may include encrypted card fields generated by the credential manager 212, requirements for retrieving and/or utilizing the shared credential, and/or a provisioning bundle ID. The provisioning bundle ID may indicate a provisioning bundle that may be utilized for provisioning the shared credential to the recipient device.

In 708, the web application 216 may transmit the information received from the credential manager 212 to the provisioning server 218. For example, the web application may transmit the encrypted card fields, the requirements, and/or the provisioning bundle ID to provisioning server 218.

In 710, the provisioning server 218 may create a card session that may be utilized for provisioning the credential to the recipient device. The provisioning server 218 may further generate a card session ID corresponding to the card session that may be utilized for identifying the card session.

In 712, the provisioning server 218 may transmit information to the user information application 222 being executed by the recipient device, where the information may be utilized for completing the provisioning of the credential to the recipient device. For example, the provisioning server 218 may transmit the card session ID generated in 710 to the user information application 222. The provisioning server 218 may further transmit a request to generate information to be used for the provisioning of the credential to the recipient device. For example, the provisioning server 218 may transmit a request for the user information application 222 to generate a privacy key, generate a public key (such as a FIDO key), and/or generate a transmission (Tx) key.

In 714, the user information application 222 may generate one or more keys. For example, the user information application 222 may generate the key or keys that are requested to be generated by the transmission of 712. In particular, the user information application 222 may generate one or more privacy keys, one or more public keys, and/or one or more Tx keys. The keys may include FIDO keys and/or device encryption keys.

In 716, the user information application 222 may provide the keys generated in 714 to the provisioning server 218. For example, the user information application 222 may provide the privacy keys, the public keys, and/or the Tx keys to the provisioning server 218. The user information application 222 may further transmit the card session ID to the provisioning server 218.

In 718, the provisioning server 218 may transmit a provisioning bundle request to the web application 216. The provisioning bundle request may include the provisioning bundle ID and/or the keys received by the provisioning server 218 in 716. The provisioning bundle request may request a provisioning bundle to be generated for the recipient device.

In 720, the web application 216 may transmit the provisioning bundle request received in 718 to the credential manager 212. The provisioning bundle request may request the credential manager 212 to generate a provisioning bundle for provisioning the shared credential to the recipient device.

In 722, the credential manager 212 may verify the provisioning bundle request. For example, the credential manager 212 may utilize the provisioning bundle ID and/or the keys received in 720 to verify that the provisioning bundle request is authorized for being performed. In particular, the credential manager 212 may determine the provisioning bundle to be retrieved by the provisioning bundle request based on the provisioning bundle ID, and may utilize the keys to verify that the recipient device is authorized to retrieve the provisioning bundle. If the credential manager 212 determines that the recipient device is authorized to retrieve the provisioning bundle, the signal flow 200 may continue. If the credential manager 212 determines that the recipient device is not authorized to retrieve the provisioning bundle, the signal flow 200 may be terminated.

FIG. 8 illustrates a seventh portion of the example signal flow 200 for sharing a credential in accordance with some embodiments. In 802, the credential manager 212 may provide a provisioning bundle to the web application 216. For example, the credential manager 212 may generate a provisioning bundle based on the reception of the provisioning bundle request received by the credential manager 212 received in 722. The provisioning bundle may provide data for provisioning the credential to the recipient device. In some embodiments, the provisioning bundle may include the credential which the recipient device may utilize for accessing the secured entity.

In 804, the web application 216 may provide credential data and/or encrypted entitlements to the provisioning server 218. For example, the web application 216 may extract the credential data and/or the encrypted entitlements from the provisioning bundle provided in 802. The credential data may include information for generating the credential on the recipient device in some embodiments. In some embodiments, the encrypted entitlements may include indications of limitations for the use of the credential by the recipient device, such as defined times when the recipient device may utilize the credential to access the secured entity.

In 806, the provisioning server 218 may generate the credential for the recipient device. For example, the provisioning server 218 may generate the credential from the credential data received in 804. Generating the credential by the provisioning server may include generating a credential in a format that can operate with platform executed by the recipient. In instances where the origination device and the recipient device execute different platforms, the format of the credential generated for the recipient device may be different than the format of the credential being utilized by the origination device.

In 808, the provisioning server 218 may provide a credential URL to the user information application 222 being executed by the recipient device. The credential URL may indicate a location from which the user information application 222 can retrieve the credential.

In 810, the user information application 222 may download the credential from the provisioning server 218. For example, the user information application 222 may access the credential from the location on the provisioning server 218 indicated by the credential URL. The user information application 222 store the credential, thereby providing the recipient device with the shared credential.

In 812, the user information application 222 may download an encrypted sharing bundle. For example, the user information application 222 may download an encrypted sharing bundle related to the credential. The encrypted sharing bundle may include encrypted information for indicating the credential and/or the secured entity to a user of the recipient device.

In 814, the user information application 222 may decrypt the encrypted sharing bundle. For example, the user information application 222 may decrypt the encrypted sharing bundle downloaded in 812 to produce the sharing bundle. The sharing bundle may include information for indicating the credential and/or the secured entity. For example, the sharing bundle may include images data and/or textual data that may be rendered within the user information application 222 to produce images and/or text that can be displayed in a user interface of the user information application 222.

In 816, the user information application 222 may store the sharing bundle. For example, the user information application 222 may store the sharing bundle in the secured element of the recipient device. The stored sharing bundle may allow the user information application 222 to display an indication of the credential and/or the secured entity for selection by the user of the recipient device. In some embodiments, the recipient device may detect a user interaction with the indication of the credential and/or the secured entity and may cause the secured entity to provide access to the user of the recipient device. In other embodiments, the secured entity may provide access based on the secured entity determining that the recipient device is located within a proximity of the secured entity and the recipient device has the credential and/or the sharing bundle stored on the recipient device.

FIG. 9 illustrates an example procedure 900 for sharing a credential by an origination device with a recipient device in accordance with some embodiments. For example, the procedure 900 may be performed by an origination device, such as the origination device 102 (FIG. 1 ). The origination device may share the credential with a recipient device, such as the recipient device 104 (FIG. 1 ) via the procedure 900. In some embodiments, the recipient device may operate a different platform than the origination device. Further, the credential being shared by the procedure 900 may be an unclonable credential. While illustrated in a certain order, it should be understood that one or more of the operations of the procedure 900 may be performed in a different order and/or concurrently. Further, operations within the procedure 900 may provide a destination of a transmission (such as an object being provided to an entity or an object being transmitted to an entity), although it should be understood that the transmission may pass through one or more entities to arrive at the destination.

In 902, the origination device may detect a user indication of a credential to be shared with the recipient device. For example, the origination device may display indications of credentials that may be shared with another device, such as the recipient device. The origination device may detect a user interaction which indicates a credential is to be shared with the recipient device, such as the user interaction detected in 226 (FIG. 2 ).

In 904, the origination device may obtain a token corresponding to the credential. For example, the origination device may obtain a token corresponding to the credential from a credential manager (such as the credential manager 212 (FIG. 2 )). The token may comprise a bearer token, such as the bearer token received in 242 (FIG. 2 ). In some embodiments, obtaining the token may include identifying entitlements, comprising an indication of the credential, which define use limitations for the credential and providing an indication of the entitlements to the credential manager. The token may be generated based at least in part on the entitlements identified.

In 906, the origination device may generate a password. For example, the origination device may generate a password for protection of the token, such as the generation of the password in 304 (FIG. 3 ).

In 908, the origination device may generate a mailbox ID for the token. For example, the origination device may generate a mailbox ID for the token, such as the generation of the mailbox ID in 306 (FIG. 3 ). In some embodiments, 908 may be omitted.

In 910, the origination device may encrypt the token. For example, the origination device encrypts the token obtained in 904, such as the encryption of the token in 314 (FIG. 3 ). In some embodiments, 910 may be omitted.

In 912, the origination device may provide the token and/or the password to a relay server (such as the relay server 210 (FIG. 2 )). For example, the origination device may provide the token and/or the password to the relay server for storage, such as the provision of the token in 316 (FIG. 3 ) and/or the provision of the password in 406 (FIG. 4 ). The recipient device may be configured to retrieve the token from the relay server with the password. In some embodiments, the token provided to the relay server may be encrypted token from 910. The relay server may be unable to decode the encrypted token.

In 914, the origination device may provide the mailbox ID to the relay server. For example, the origination device may provide the mailbox ID to relay server with the token and the password. The relay server may be configured to store the token associated with the mailbox identifier and identify the token for retrieval by the recipient device based at least in part on the mailbox identifier. In some embodiments, 914 may be omitted.

In 916, the origination device may detect a key. For example, the origination device may detect a key provided by the recipient device, such as the key received in 518 (FIG. 5 ). In some embodiments, the key may comprise a public key of an asymmetric key pair generated by the recipient device. In some embodiments, 916 may be omitted.

In 918, the origination device may generate a signature. The origination device may generate the signature based at least in part on the key detected in 916, such as the generation of the signature in 522 (FIG. 5 ). In some embodiments, the signature may cover the public key detected in 916. For example, the signature being based on the public key may allow the signature to represent the public key.

In 920, the origination device may provide the signature to the recipient device. For example, the origination device may provide the signature to the recipient device, such as the signature being provided in 604 (FIG. 6 ). The recipient device may be configured to use the signature for provisioning of the credential.

FIG. 10 illustrates another example procedure 1000 for sharing a credential by an origination device with a recipient device in accordance with some embodiments. For example, the procedure 1000 may be performed by an origination device, such as the origination device 102 (FIG. 1 ). The origination device may share the credential with a recipient device, such as the recipient device 104 (FIG. 1 ) via the procedure 1000. In some embodiments, the recipient device may operate a different platform than the origination device. Further, the credential being shared by the procedure 1000 may be an unclonable credential. While illustrated in a certain order, it should be understood that one or more of the operations of the procedure 1000 may be performed in a different order and/or concurrently. Further, operations within the procedure 1000 may provide a destination of a transmission (such as an object being provided to an entity or an object being transmitted to an entity), although it should be understood that the transmission may pass through one or more entities to arrive at the destination.

In 1002, the origination device may display an indication of a credential. For example, the origination device may display an indication that the credential can be shared with a recipient, such as the presentation of credentials that can be shared in 228 (FIG. 2 ).

In 1004, the origination device may detect a user selection of the credential. For example, the origination device may detect a user selection of the credential to be shared with the recipient device, such as the user selection in 230 (FIG. 2 ).

In 1006, the origination device may obtain a token. For example, the origination device may obtain a token corresponding to the credential, such as the reception of the bearer token in 244 (FIG. 2 ) or 302 (FIG. 3 ).

The block diagram of FIG. 12 is intended to show a high-level view of some of the components of the UE 1200. However, some of the components shown may be omitted, additional components may be present, and different arrangement of the components shown may occur in other implementations.

The components of the UE 1200 may be coupled with various other components over one or more interconnects 1232, which may represent any type of interface, input/output, bus (local, system, or expansion), transmission line, trace, optical connection, etc. that allows various circuit components (on common or different chips or chipsets) to interact with one another.

The processors 1204 may include processor circuitry such as, for example, baseband processor circuitry (BB) 1204A, central processor unit circuitry (CPU) 1204B, and graphics processor unit circuitry (GPU) 1204C. The processors 1204 may include any type of circuitry or processor circuitry that executes or otherwise operates computer-executable instructions, such as program code, software modules, or functional processes from memory/storage 1212 to cause the UE 1200 to perform operations as described herein.

The PMIC 1224 may manage power provided to various components of the UE 1200. In particular, with respect to the processors 1204, the PMIC 1224 may control power-source selection, voltage scaling, battery charging, or DC-to-DC conversion.

In some embodiments, the PMIC 1224 may control, or otherwise be part of, various power saving mechanisms of the UE 1200. For example, if the platform UE is in an RRC_Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the UE 1200 may power down for brief intervals of time and thus save power. If there is no data traffic activity for an extended period of time, then the UE 1200 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The UE 1200 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The UE 1200 may not receive data in this state; in order to receive data, it must transition back to RRC_Connected state. An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.

A battery 1228 may power the UE 1200, although in some examples the UE 1200 may be mounted deployed in a fixed location, and may have a power supply coupled to an electrical grid. The battery 1228 may be a lithium ion battery, a metal-air battery, such as a zinc-air battery, an aluminum-air battery, a lithium-air battery, and the like. In some implementations, such as in vehicle-based applications, the battery 1228 may be a typical lead-acid automotive battery.

The recipient device may be, or may include one or more of the features of, the recipient device 104. The recipient device may execute a different platform than the origination device. The user information application 1322 may be a user information application for the platform executed by the recipient device, whereas the user information application 1302 may be a user information application for the platform executed by the origination device. The user information application 1322 may store one or more credentials that allow the recipient device to access a secured entity.

In 1324, the user information application 1302 of the origination device may detect a user interaction from a user of the origination device that indicates the user desires to share a credential. For example, the user information application 1302 may be executed by the origination device and may present a user interface on a display of the origination device. The origination device may detect a user indication with the user interface displayed by the origination device that indicates the user desires to share a credential.

In 1326, the user information application 1302 may read shareable entitlements from the origination device. For example, the user information application 1302 may determine credentials that are available in the user information application 1302, which may be one or more of the credentials stored by the origination device. From the credentials, the user information application 1302 may determine which of the credentials are shareable. For example, stored data associated with the credentials may indicate which of the credentials are shareable in some embodiments.

In 1328, the user information application 1302 may present indications of the shareable credentials to the user of the origination device. In particular, the user information application 1302 may display a user interface on the display of the origination device that indicates the credentials available in the user information application 1302 that are shareable. The user interface may allow the user to select one or more of the shareable credentials to be shared by the user information application 1302.

In 1330, the user information application 1302 may detect a user interaction from the user that indicates which of the shareable credentials the user selects to share. For example, the user may interact with the user interface display by the user information application in 1328 to indicate which of the displayed shareable credentials the user selects to share. The origination device may detect the user interaction and the user information application 1302 may determine which credentials are to be shared based on the user interaction. In some embodiments, the user may further define limitations for sharing of the credentials. For example, the user may indicate a time period for which the sharing of the credentials is to remain valid, times of day and/or week that a device with which the credentials are being shared may utilize the credentials, a particular entity access point (for example, if a secured entity includes multiple entity access points (such as multiple doors), a particular entity access point (such as a certain door of the multiple doors) may be defined for providing access to the secured entity), or other limitations for the use of the credentials.

In 1332, the user information application 1302 may detect a user interaction from the user indicating that the sharing of the selected credentials is to be initiated. For example, the user may interact with a user interface displayed on the display of the origination device that indicates that the user information application 1302 is to share the selected credentials. The user information application 1302 may detect the user interaction and initiate the procedure for sharing the credentials.

In 1334, a credential authority operation may be performed. In some embodiments where the credential is maintained by the credential manager 1312, the credential authority operation may be defined by the credential manager 1312 and may be utilized by the credential manager 1312 to verify that the originating device has authorization to share the credential. For example, the credential authority operation may result in the credential manager 1312 receiving information related to the originating device that the credential manager 1312 can utilize to determine whether the originating device is authorized to share the credential. In some embodiments where the credential manager 1312 determines that the origination device is authorized to share the credential, the credential manager 1312 may provide a share voucher (which may also be referred to as a token) to the origination device as part of the credential authority operation, where the share voucher may be utilized to share the credential with the recipient device. The user information application 1302 may further generate a pin code that can be utilized for sharing the credential with the recipient device as part of the credential authority operation.

In other embodiments where the credential is maintained by the originating device, the user information application 1302 may generate a share voucher. The share voucher may be utilized to share the credential with the recipient device. The user information application 1302 may further generate a pin code that can be utilized for sharing the credential with the recipient device as part of the credential authority operation.

In 1336, the user information application 1302 may generate a key. The key generated by the user information application 1302 may be a relay symmetric key. In some embodiments, the key may be an AES key. The user information application 1302 may derive the key from salt and/or a number of iterations.

In 1338, the user information application 1302 may securely store the key with a mailbox ID. 1338 may be performed as part of a stateful key exchange for stateful credential sharing. 1338 may be omitted in stateless credential sharing. The key may be utilized to encrypt stateful payloads in the stateful credential sharing. The user information application 1302 may store the key in a secure element of the origination device, where the secure element may comprise a chip within the origination device that is designed to be protected from unauthorized access. The secure element may limit a set of applications that are allowed to access the chip and/or write to the chip.

In 1402, the user information application 1302 may generate an encrypted payload. The user information application 1302 may generate the encrypted payload by encrypting metadata and/or the pin code. The user information application 1302 may perform AES encryption with the bearer token and/or the sender push token to produce the encrypted payload. The encryption of the payload may prevent one or more of the entities (such as the provisioning server 1306, the relay server 1310, the web application 1316, and/or the provisioning server 1318) from being able to read bearer token and/or the sender push token. In some embodiments, 1402 may be omitted.

In 1404, the user information application 1302 may generate an encrypted payload. The user information application 1302 may generate the encrypted payload by encrypting metadata. The user information application 1302 may perform AES encryption with the bearer token and/or the sender push token to produce the encrypted payload. The encryption of the payload may prevent one or more of the entities (such as the provisioning server 1306, the relay server 1310, the web application 1316, and/or the provisioning server 1318) from being able to read bearer token and/or the sender push token. In some embodiments, 1404 may be omitted. In some embodiments, 1402 and 1404 may be performed in the alternative, where 1402 may be performed in some embodiments and 1404 may be performed in other embodiments.

In 1406, the user information application 1302 may provide the encrypted payload and/or display information to the relay server 1310. The user information application 1302 may further provide configuration information, the mailbox ID, and/or a sender push token along with the encrypted payload and/or the metadata. The configuration information may indicate authorization policies to be implemented by the relay server 1310 when sharing the credentials. The available policies may include stateless (which may allow a single write), stateful (which may allow two writes), and/or long lived (which may allow infinite writes, signatures).

In some embodiments, the user information application 1302 may further provide an attestation in 1406. The attestation may comprise a signature applied to the data, or some portion thereof, transmitted in 1406. The attestation may be associated with the origination device executing the user information application 1302 and may be utilized for determining that the origination device is a valid device for requesting the sharing of the credential. The attestation may limit or be devoid of information that can identify a user of the origination device. Accordingly, the relay server 1310 may be unable to identify a user of the origination device based on the attestation, which can protect the identity of the user and/or credentials associated with the user. The relay server 1310 may utilize the attestation to determine that the device requesting the sharing of the credential is a type of device that is authorized to share the credential. For example, the relay server 1310 may be aware that a smartphone device is authorized to share the credential. If the relay server 1310 determines that the device requesting the sharing of the credential is a smartphone device based on the attestation, the relay server 1310 may allow the signal flow 1300 to continue. However, if the relay server 1310 determines that the device requesting the sharing of the credential is another type of device (such as another server), the relay server 1310 may terminate the signal flow 1300. In some embodiments, the attestation may be omitted.

In 1408, the relay server 1310 may convert the display information to rich object data. The display information may include an indication of the secured entity to which the credential can provide access. A device may utilize the rich object data to display an indication of the secured entity on the device.

In 1410, the relay server 1310 may store the mailbox ID, the display information, the metadata, the sender push token, and/or the rich object data produced from the metadata in a location associated with the mailbox ID. For example, the relay server 1310 may store the display information, the metadata, the sender push token, and/or the rich object data produced from the metadata, where the location can be identified based on the mailbox ID. Further, the relay server 1310 may associate the authorization policy indicated by the configuration information with the storage location, such that the relay server 1310 may apply the authorization policy for any device attempting to access the storage location via the mailbox ID.

In 1412, the relay server 1310 may provide a universal share URL to the user information application 1302. The universal share URL may correspond to the storage location associated with the mailbox ID. A device that enters the universal share URL may be directed to the storage location and may, when authenticated, be able to retrieve information from the storage location. The relay server 1310 may provide the universal share URL to the user information application 1302 for sharing with the recipient device to retrieve the display information, the metadata, the sender push token, and/or the rich object data stored in the storage location.

In 1414, the user information application 1302 may launch the communication application 1304 for sharing the universal share URL received in 1412 and/or the relay symmetric key generated in 1336. For example, the user information application 1302 may cause the universal share URL and/or the relay symmetric key to be provided to the communication application 1304 for sharing with another device, such as the recipient device. The user information application 1302 may transmit the password out of band for increased security. For example, the user information application 1302 may transmit the relay symmetric key in a different communication from the token to provide for increased security.

In 1416, the communication application 1304 associated with the origination device may transmit the universal share URL and/or the relay symmetric key to the communication application 1320 associated with the origination device. For example, the communication application 1304 being executed by the origination device may transmit the universal share URL and/or the relay symmetric key in a message to the communication application 1320 being executed by the recipient device.

In 1418, the user information application 1302 may provide pin code and/or a pin code URL to the communication application 1320. The user information application 1302 may provide the pin code and/or the pin code URL over another channel from the universal share URL and/or the relay symmetric key transmitted in 1416. The pin code and/or the pin code URL may be sent via an application supported by both the originating device and the recipient device, such as What's App, short message service (SMS), and/or electronic mail (Email).

FIG. 15 illustrates a third portion of the example signal flow 1300 for sharing a credential in accordance with some embodiments. In 1502, the communication application 1320 associated with the recipient device may utilize the universal share URL received in 1416 to request information from the relay server 1310 associated with mailbox ID. For example, the communication application 1320 may transmit a request to the relay server 1310 to provide at least a portion of the information associated with the universal share URL, which may be the storage location on the relay server 1310 associated with the mailbox ID.

In 1504, the relay server 1310 may provide the display information to the communication application 1320. For example, the relay server 1310 may retrieve the display information from the storage location based on the request received in 1502 and transmit the display information to the communication application 1320 being executed on the recipient device.

In 1506, the communication application 1320 may display a snapshot corresponding to the rich object data on the display of the recipient device. For example, the rich object data may include an indication of the secured entity for which the shared credential may provide access. The communication application 1320 may cause the indication of the secured entity to be displayed on the display of the device. The indication may include a description of the secured entity, an image associated with the secured entity, or some other visual representation related to the secured entity that may be displayed on the display of the recipient device.

In 1508, the communication application 1320 may provide the universal share URL and/or the password received in 1418 to the user information application 1322 executing on the recipient device. In some embodiments, the communication application 1320 may provide the universal share URL and/or the password to the user information application 1322 based on a user interaction with the indication of the secured entity displayed on the display of the device in 1506. The communication application 1320 may cause the user information application 1322 to launch along with providing in the universal share URL and/or the password.

In 1510, the user information application 1322 may transmit a request to the relay server 1310 to provide the information from the mailbox. For example, the user information application 1322 may transmit a request that includes the mailbox ID indicating the mailbox from which the data is being requested.

In 1512, the relay server 1310 may provide the rich object data generated from the metadata and/or the encrypted payload to the user information application 1322. The relay server 1310 may provide the rich object data and/or the encrypted payload based on the reception of the request received from the user information application 1322 in 1510.

In 1514, the user information application 1322 may generate a key. In particular, the user information application 1322 may generate the key based on the rich object data, the salt, the mailbox ID, the relay password, and/or the iterations. The key may be a symmetric key in some embodiments. The user information application 1322 may derive an AES key from the rich object data, the salt, the mailbox ID, the password, and/or the iterations to produce the key.

In 1516, the user information application 1322 may decrypt the encrypted payload received in 1512 with the key generated in 1514. The user information application 1322 may produce the share voucher and/or the pin code by decrypting the encrypted payload.

1518 through 1710 (FIG. 17 ) may be performed in some instances and may be omitted in other instances. For example, 1518 through 1710 may be performed for stateful key exchanges, whereas 1518 through 1710 may be omitted for stateless key exchanges. Whether the exchange is stateful or stateless may be defined based on configuration defined in 1406.

In 1518, the user information application 1322 may securely store the key produced in 1514 with association to the mailbox ID. The user information application 1322 may store the key in a secure element of the recipient device.

In 1520, the user information application 1322 may generate a key pair. For example, the user information application 1322 may generate the key pair based on the metadata for provisioning information in accordance with key requirements. The key pair may be an asymmetric key pair in some embodiments, where the asymmetric key pair may comprise a public key and a corresponding private key. The public key may be referred to as a transaction key.

FIG. 16 illustrates a fourth portion of the example signal flow 1300 for sharing a credential in accordance with some embodiments. In 1602, the user information application 1322 may encrypt the transaction key of the key pair generated in 1520. The user information application 1322 may perform AES encryption with the public key of the key pair.

In 1604, the user information application 1322 may transmit the public key of the key pair generated in 1520 to the relay server 1310. For example, the user information application 1322 may transmit the encrypted public key, which was encrypted in 1602, to the relay server 1310. The user information application 1322 may further transmit the mailbox ID and/or the sender push token to the relay server 1310 with the encrypted public key. The relay server 1310 may store the encrypted public key based on the reception of the encrypted public key.

In some embodiments, the user information application 1322 may further provide an attestation in 1604. The attestation may comprise a signature applied to the data, or some portion thereof, transmitted in 1604. The attestation may be associated with the recipient device executing the user information application 1322 and may be utilized for determining that the recipient device is a valid device for obtaining the shared credential. The attestation may limit or be devoid of information that can identify a user of the recipient device. Accordingly, the relay server 1310 may be unable to identify a user of the recipient device based on the attestation, which can protect the identity of the user and/or credentials associated with the user. The relay server 1310 may utilize the attestation to determine that the device requesting the shared credential is a type of device that is authorized to receive the credential. For example, the relay server 1310 may be aware that a smartphone device is authorized to receive the credential. If the relay server 1310 determines that the device requesting the credential is a smartphone device based on the attestation, the relay server 1310 may allow the signal flow 1300 to continue. However, if the relay server 1310 determines that the device requesting the credential is another type of device (such as another server), the relay server 1310 may terminate the signal flow 1300. In some embodiments, the attestation may be omitted.

In 1606, the relay server 1310 may request a push notification from the push notification system 1308 associated with the origination device. The push notification request may include the mailbox ID, the sender push token, and/or the public key. The push notification request may request that the push notification system 1308 provide a push notification to the user information application 1302 that indicates a recipient device is attempting to retrieve the shared credential.

In 1608, the push notification system 1308 may send a push notification to the user information application 1302 on the origination device. The push notification may cause a user interface to be displayed on a display of the origination device. The user interface displayed on the origination device may indicate that a recipient device is attempting to retrieve the shared credential. In some embodiments, the user interface displayed on the origination device may further request input from a user of the origination device to indicate that the recipient device is authorized to receive the shared credential. By utilizing the push notification system 1308, the notification may be provided when recipient device is attempting to retrieve the credential and/or as soon as the origination device is available to receive push notifications after the recipient device has attempted to retrieve the credential.

In 1610, the user information application 1302 may send a request to the relay server 1310 to retrieve information from the relay server 1310. The information requested by the user information application 1302 may include the encrypted public key that was stored in 1604.

In 1612, the relay server 1310 may transmit information to the user information application 1302 based on the request from 1610. For example, the relay server 1310 may transmit the encrypted public key to the user information application 1302.

In 1614, the user information application 1302 may decrypt the information received from the relay server 1310. For example, the user information application 1302 may decrypt the transaction key received in 1612. Decrypting the transaction key may produce the transaction key.

In 1616, the user information application 1302 may generate a signature. For example, the wallet key may generate a signature based on the transaction key and/or the mailbox ID. The signature may cover the transaction key that was produced through the decryption in 1614. In some embodiments, the signature may include an attestation, a token, and/or entitlements. In some embodiments, the signature may be used in place of the bearer token going forward in the signal flow 1300.

In 1618, the user information application 1302 may encrypt the signature to produce an encrypted payload. For example, the user information application 1602 may encrypt the signature generated in 1616 using AES encryption to produce the encrypted payload.

In 1620, the user information application 1302 may provide the encrypted payload to the relay server 1310 for storage. The user information application 1302 may further provide the receiver push token, and/or the mailbox ID to the relay server 1310 with the encrypted payload. The relay server 1310 may store the encrypted payload when received. For example, the relay server 1310 may store the encrypted payload in a storage location corresponding to the mailbox ID. Due to the encrypted payload being encrypted, the relay server 1310 may be unable to read the data within the encrypted payload.

FIG. 17 illustrates a fifth portion of the example signal flow 1300 for sharing a credential in accordance with some embodiments. In 1702, the relay server 1310 may transmit a request for a push notification to the push notification system 1314 associated with the recipient device. The request may include the mailbox ID and/or the receiver push token.

In 1704, the push notification system 1314 may transmit a push notification to the user information application 1322 executed by the recipient device. The push notification system 1314 may transmit the push notification based on the request for the push notification received by the push notification system in 1702. The push notification may cause a user interface to be displayed on a display of the recipient device. The push notification may include the mailbox ID and/or the receiver push token.

In 1706, the user information application 1322 may transmit a request for information to the relay server 1310. For example, the user information application 1322 may transmit a request for the relay server 1310 to provide at least a portion of the information stored in the storage location corresponding to the mailbox ID.

In 1708, the relay server 1310 may transmit the encrypted payload stored in the storage location corresponding to the mailbox ID to the user information application 1322. For example, the relay server 1310 may transmit the encrypted payload stored in 1620 to the user information application 1322. The encrypted payload may include the encrypted signature.

In 1710, the user information application 1322 may decrypt encrypted payload received from the relay server 1310 in 1708. For example, the user information application 1322 may perform AES decrypting with the encrypted payload. The decryption of the encrypted payload may produce the signature.

1712 through 1904 (FIG. 19 ) may be performed in some instances and may be omitted in other instances. For example, 1712 through 1904 may be performed for stateless key exchanges, whereas 1712 through 1904 may be omitted for stateful key exchanges. Whether the exchange is stateful or stateless may be defined based on configuration defined in 1406.

In 1712, the user information application 1322 of the recipient device may provide a request to the provisioning server 1318 to retrieve the credential. The request may include an indication of the provisioning target (which may be the credential) and/or provisioning information (which may be information related to the credential). The request may further include a pin code that a user of the recipient device may have input to the recipient device and/or that is associated with a URL selected by the user on the recipient. The provisioning server 1318 may utilize the pin code along with the provisioning target to determine whether the user of the recipient device is authorized to retrieve the credential.

In 1714, the provisioning server 1318 may provide a redemption request for the credential to the web application 1316. The redemption request may include an indication of the provisioning target and/or the pin code.

In 1716, the web application 1316 may determine a partner corresponding to the redemption request. For example, the web application 1316 may determine the credential manager corresponding to the credential to be retrieved.

In 1718, the web application 1316 may provide a credential request to the credential manager 1312. The credential request may indicate that the web application 1316 and/or the user information application 1322 is requesting the credential. The credential request may include a sharing instance ID, a provisioning credential ID, and/or a pin code.

In 1720, the credential manager 1312 may provide information for the credential manager 1312 to verify the recipient device and/or the user is authorized to retrieve the credential to the web application 1316. The information may include encrypted card fields, requirements for credential retrieval, a provisioning bundle ID, and/or a FIDO profile for verifying the authorization.

In 1722, the web application 1316 may provide the information received in 1720 to the provisioning server 1318. For example, the web application 1316 may provide the encrypted card fields, the requirements for credential retrieval, the provisioning bundle ID, and/or the FIDO profile to the provisioning server 1318.

FIG. 18 illustrates a sixth portion of the example signal flow 1300 for sharing a credential in accordance with some embodiments. In 1802, the provisioning server 1318 may create a card session. The card session may be utilized for provisioning the credential to the user information application 1322. The provisioning server 1318 may further generate a card session ID corresponding to the card session.

In 1804, the provisioning server 1318 may provide authentication generation information to the user information application 1322. For example, the authentication generation information may indicate the information to be produced by the user information application to be utilized for verifying authorization by the credential manager 1312. The authentication generation information may include the card session identifier, the requirements, a privacy key generation indication, a generate FIDO indication, and/or a transmission key generation indication.

In 1806, the user information application 1322 may generate one or more keys. For example, the user information application 1322 may generate one or more keys in accordance with the authentication generation information received in 1804. The keys generate may include a privacy key, a transmission key, and/or FIDO information.

In 1808, the user information application 1322 may transmit an enable card request to the provisioning server 1318. The enable card request may include the card session identifier, the privacy key, the transmission key, and/or the FIDO information. The enable card request may request enablement of the card session.

In 1810, the provisioning server 1318 may request a provisioning bundle associated with the credential from the web application 1316. The provisioning bundle request may include a provisioning bundle ID, the privacy key, the transmission key, and/or the FIDO information.

In 1812, the web application 1316 may provide the provisioning bundle request to the credential manager 1312. The provisioning bundle request may request that the credential manager provide a copy of the credential to the user information application 1322. The provisioning bundle request may include the provisioning bundle ID, the privacy key, the transmission key, and/or the FIDO information.

In 1814, the credential manager 1312 may verify the authorization for credential. For example, the credential manager 1312 may verify that the user and/or the recipient device is authorized to receive the credential. The credential manager 1312 may determine the provisioning bundle corresponding to the credential for which authorization is being sought based on the provisioning bundle ID. The credential manager 1312 may determine whether the user and/or recipient device is authorized based on the FIDO information, privacy key, and/or the transmission key. The signal flow 1300 may proceed if it is determined that the user and/or the recipient device is authorized to retrieve the credential. If the credential manager 1312 determines that the user and/or the recipient device is not authorized to retrieve the credential, the signal flow 1300 may be terminated.

In 1816, the credential manager 1312 may store the keys. For example, the credential manager 1312 may store the keys received in 1812. The keys stored may include the privacy key and/or the transmission key.

In 1818, the credential manager 1312 may provide credential information to the web application 1316. The credential information may include information for provisioning the credential to the user information application 1322. For example, the credential information may include a bundle corresponding to the credential and/or device encrypted entitlements.

In 1820, the web application 1316 may provide credential provisioning information to the provisioning server 1318. The credential provisioning information may include pass data for creating a pass related to the credential for the user information application 1322. The credential provisioning information may further include encrypted entitlements.

FIG. 19 illustrates a seventh portion of the example signal flow 1300 for sharing a credential in accordance with some embodiments. In 1902, the provisioning server 1318 may create a pass. For example, the provisioning server 1318 may create a pass corresponding to the credential.

In 1904, the provisioning server 1318 may provide a credential URL to the user information application 1322 being executed by the recipient device. The credential URL may indicate a location from which the user information application 1322 can retrieve the credential.

In 1906, the user information application 1322 may download the credential from the provisioning server 1318. For example, the user information application 1322 may access the credential from the location on the provisioning server 1318 indicated by the credential URL. The user information application 1322 store the credential, thereby providing the recipient device with the shared credential.

In 1908, the user information application 1322 may download an encrypted sharing bundle. For example, the user information application 1322 may download an encrypted sharing bundle related to the credential. The encrypted sharing bundle may include encrypted information for indicating the credential and/or the secured entity to a user of the recipient device.

In 1910, the user information application 1322 may decrypt the encrypted sharing bundle. For example, the user information application 1322 may decrypt the encrypted sharing bundle downloaded in 1908 to produce the sharing bundle. The sharing bundle may include information for indicating the credential and/or the secured entity. For example, the sharing bundle may include images data and/or textual data that may be rendered within the user information application 1322 to produce images and/or text that can be displayed in a user interface of the user information application 1322.

In 1912, the user information application 1322 may store the sharing bundle. For example, the user information application 1322 may store the sharing bundle in the secured element of the recipient device. The stored sharing bundle may allow the user information application 1322 to display an indication of the credential and/or the secured entity for selection by the user of the recipient device. In some embodiments, the recipient device may detect a user interaction with the indication of the credential and/or the secured entity and may cause the secured entity to provide access to the user of the recipient device. In other embodiments, the secured entity may provide access based on the secured entity determining that the recipient device is located within a proximity of the secured entity and the recipient device has the credential and/or the sharing bundle stored on the recipient device.

It is well understood that the use of personally identifiable information should follow privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining the privacy of users. In particular, personally identifiable information data should be managed and handled so as to minimize risks of unintentional or unauthorized access or use, and the nature of authorized use should be clearly indicated to users.

For one or more embodiments, at least one of the components set forth in one or more of the preceding figures may be configured to perform one or more operations, techniques, processes, or methods as set forth in the example section below. For example, the baseband circuitry as described above in connection with one or more of the preceding figures may be configured to operate in accordance with one or more of the examples set forth below. For another example, circuitry associated with a UE, base station, network element, etc. as described above in connection with one or more of the preceding figures may be configured to operate in accordance with one or more of the examples set forth below in the example section.

In some embodiments, some or all of the operations described herein can be performed using an application executing on the user's device. Circuits, logic modules, processors, and/or other components may be configured to perform various operations described herein. Those skilled in the art will appreciate that, depending on implementation, such configuration can be accomplished through design, setup, interconnection, and/or programming of the particular components and that, again depending on implementation, a configured component might or might not be reconfigurable for a different operation. For example, a programmable processor can be configured by providing suitable executable code; a dedicated logic circuit can be configured by suitably connecting logic gates and other circuit elements; and so on.

As described above, one aspect of the present technology is the gathering, sharing, and use of data, including an authentication tag and data from which the tag is derived. The present disclosure contemplates that, in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter ID's, home addresses, data or records relating to a user's health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information.

The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to authenticate another device, and vice versa to control which device ranging operations may be performed. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be shared to provide insights into a user's general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals.

The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence, different privacy practices should be maintained for different personal data types in each country.

Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of sharing content and performing ranging, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, users may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app.

Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user's privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data at a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods.

Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data.
